The battle royale tournament is the final tournament you unlock and is comprised of every single type of game type.

Getting gold on the tournament means that you earned more points in the games throughout the tournament than anyone else. Only gold, silver, and bronze finishers earn any points so try to finish in the top three if not at number one.

If you earn platinum (finish first on each event) you still unlock the achievement.

You back flip off basically every jump in the game by simply holding back on the while going up the jump and then continuing to hold it while you are in mid-air.

I personally like to do the target time trial on the street mode of the zone Red Hook. At the start of the game you will come up to a large ramp. Use your boost to quickly go up the ramp and get some extra air. Hold back on the while you're going up and when you land you should have the achievement.

While playing through tournaments you may notice that you recieve money and then in turn between events you can purchase upgrades for your board and weapons. You have to take all that money and max out each of your boards stats.

The minimum amount of money you will need to max out your weapons/boards is 288,000. Since you start off with 14,000 dollars you only need 274,000. You can get one or two grand each time you touch a green $ symbol floating around in the levels.

You must upgrade you board/weapons to their max in just one tournament. Otherwise the stats will reset and you will have to start over. I reccommend using the following settings against one AI on alocal play Cash Tournament.

Cash Tournament

Arena

Long

Takedown

Focus solely on grabbing all the money before you kill your enemy. Since long gives you twenty rounds and you need 274,000 dollars you will need 13,700 dollars per round.

Also I reccommend you upgrade your board first since the weapons won't be useful for collecting money.

When it says "take down an opponent while on a grind" it means that you must be grinding.

This can be done in on or offline mode. I reccomend doing a tournament and focusing on upgrading your favorite weapon (I reccomend the rocket launcher) so that you can quickly kill someone who is likely to be far away.

Once you get to an arena with a grind rail (I reccomend the level "Governor's Island") jump onto the grind rail with and then fire off as many rounds at an enemy as you can. Hopefully you will get a kill and if not just jump back onto the rail and try again.

This can be done on any level but I reccomend doing it on the level "Governor's Island" in a local play game with some AI (or if you have them, additional controllers work well.)

Set it to one AI with the settings as follows.

Exhibition

Arena

Governors Island

Takedown

Once you're inside the game simply start cruising around the outside of the map (the area that is inside accessible by the openings on the north and south side of the main portion of the map) grabbing all the upgrades you can. Occasionally the ?s will give you invincibility. If they do go ahead and turn around and kill the enemy chasing you (which they normally do) while you are invincible.

Once you've got a fully upgraded weapon go ahead and slaughter the AI with it, if you need to grab some health or simply keep looking for the invincibility.
